Big idea-Negative numbers help us to model many real world situations
Essential question- How do we multiply and divide integers

B On grid paper, sketch a graph of y=3x+2.
C Enter the equation y=3x+2 into your graphing calculator, and press graph. Make a sketch of the graph you see. How does this graph compare to the graph you drew by hand?
The graph i drew by hand was almost the almost the same but a little wider than the actual graph on the graphing calculator.
2 How does this graph compare to the graph you saw in part b?
Ans- This graph looks like the part of the graph I drew in part b. It is part of the first quadrant. 3 How does this graph compare with the graph you made with your calculator in part c? Ans- It is part of the same graph I drew in part c. 4 Explain what you think each entry on the window setting 1 screen means.
It is the thing that gives the coordinates to the calculator for the line to be drawn on the calculator. E On paper, make a table of the x and y values for the equation y=2x.

F On grid paper, sketch a graph of y=2x.
G Enter the equation y=2x into your calculator and press graph. Make a sketch of the graph you see.
2 How does the graph compare with the graph you drew in part F? The line on the graph is abit more tilted than the one i drew by hand 3 How does compare this graph compare with the graph you made with your calculator in part G?
Its abit like the graph in part f. Its abit more tilted. 4 Explain what you think each entry on the window settings 2 screen means.
I think it is the thing that give the calculator the coordinates to draw the lines on the graph.
